Abstract
A garter-type axially resilient coil spring includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and a leading portion. Specific resilient performance, or load-deflection characteristics, of the spring is obtained by interconnecting the coils in a manner such that the trailing portion is disposed along an outside diameter of the garter-type axially resilient coil spring and the leading portion is disposed along an inside diameter of the garter-type axially resilient coil spring.
